About this network

The AS handle UMWWM-AS is held by Województwo Warmińsko-Mazurskie, the administrative region of Warmian-Masurian Voivodeship in Poland.

What it's used for

• The space carries a single IPv4 prefix, 213.73.31.0/24, with the netname UMWWM and registrant abuse OLMAN.
• The inventory consists of 256 IPv4 addresses across 1 prefix, with 0 IPv6 prefixes announced.
• With only 2 observed neighbours, the low neighbour count relative to the address space suggests a limited connectivity footprint typical of a specific institutional or administrative network rather than a transit provider.

Notable

• The registrant abuse OLMAN for the prefix 213.73.31.0/24 differs from the AS holder name, indicating potential historical registration or specific abuse contact designation.
• The address inventory is minimal, consisting of a single /24 block, which aligns with the needs of a regional government administrative body rather than a large-scale ISP or hosting provider.
